It is a partial embodiment of the invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of Embodiment 1 of a method for controlling a wireless router according to the present invention. As shown in FIG. 1, the method includes:

Step 101: Detect whether the wireless router is connected to the terminal.

The execution body of this embodiment may be a wireless router. The wireless router can be powered by an external power source or by a battery. The terminal in this embodiment may be a terminal device such as a computer or a mobile phone that can access the network through a wireless router. The wireless router is used to complete data forwarding between terminals or between the terminal and the network.

The wireless router detects whether the wireless router is connected to the terminal. The specific detection method may include: 1. If the wireless router does not forward the data for a period of time, the connection detection is performed on the IP address of the terminal without data activity, if the connection continues for a period of time. If the time is not responding, it is confirmed that the wireless router is not connected to the terminal. If there is a response, it is confirmed that the wireless router is currently connected to the terminal; 2. Whether a logical connection between the wireless router and the terminal is established on the air interface is detected. If not, confirm that the wireless router is not connected to the terminal, and if so, confirm that the wireless router is currently connected to the terminal.

Step 102: If the wireless router is not connected to any terminal, the wireless router is turned off.

If the wireless router detects that there is no connection between the wireless router and any of the terminals, the wireless router is turned off, thereby enabling the wireless router to be turned off when idle, reducing power consumption, saving energy, and avoiding inefficient consumption. Especially when the wireless router is powered by a battery, the power consumption of the battery can be reduced.

In the embodiment of the present invention, the wireless router can detect whether the wireless router is connected to the terminal, and when the wireless router is not connected to any terminal, shut down the wireless router; thereby enabling the wireless router to automatically shut down when idle, thereby Save energy and avoid inefficient consumption.

2 is a flowchart of Embodiment 2 of a method for controlling a wireless router according to the present invention. As shown in FIG. 2, the method includes:

Step 201: Detect whether the wireless router is connected to the terminal.

The execution body of this embodiment may be a wireless router. The step of the wireless router detecting whether the wireless router is connected to the terminal may specifically include step 201a or step 201b.

Step 201a: If the wireless router does not forward data in the first preset time, perform connection detection on the IP address of the terminal that has no data transmission in the second preset time, and if the response is received, detect that the wireless router is connected to the terminal. If the response is not received, it is detected that the wireless router has no connection with the terminal; specifically, if the wireless router does not forward data within a certain period of time (the first preset time), there is no data transmission in the second preset time. The terminal's IP address is detected by the connection. If the response of the terminal is received within a preset time (for example, tl), it indicates that the wireless router is connected to the terminal, if it is not received within a preset time (for example, tl) The response to the terminal indicates that the wireless router is not connected to the terminal; wherein, the connection detection performed by the foregoing may be: a PING (Packet Internet Grope) test; or, the connection detection may be, for example, a router The terminal to be detected sends a data packet for connection detection, according to whether it is received Responder to determine whether the router is connected to the terminal.

The process of obtaining the IP address of the terminal that has no data transmission in the second preset time may include: the wireless router acquiring the IP address corresponding to the terminal from the data packet sent by the network side or the terminal, if in the second preset time If the data packet corresponding to the IP address is not received again, the IP address is The IP address of the terminal that has no data transmission in the second preset time; specifically, the wireless router receives the data packet sent by the network side or the terminal, obtains the IP address corresponding to the terminal from the data packet, and starts timing. If the wireless router does not receive the data sent by the IP address or the data sent to the IP address in the second preset time, it is confirmed that the IP address is the IP of the terminal that has no data transmission within the second preset time. address.

It should be noted that the first preset time and the second preset time may be set according to actual conditions. Among them, PING is a DOS (Disk Operating System) command, which is generally used to detect network access and nowhere. Specifically, PING can be the "echo request" message sent by the local end to the IMCP protocol. The echo reply" message proves that the local end is connected to the peer.

In step 201b, it is detected whether a logical connection between the wireless router and the terminal is established on the air interface. If there is a logical connection, it is detected that the wireless router is connected to the terminal. If there is no logical connection, it is detected that the wireless router has no connection with the terminal.

If the terminal is connected to the wireless router, the terminal establishes a logical connection with the wireless local area network (Wireless Local Area Networks, WLAN for short) on the air interface. Therefore, the wireless router can know whether there is a connection between the terminal and the wireless router by detecting whether a logical connection is established on the air interface.

Before detecting whether a logical connection between the wireless router and the terminal is established on the air interface, the wireless router may first detect whether the wireless router forwards data. If the data is not forwarded, whether the air interface is established between the wireless router and the terminal is detected. Logical connection.

Step 202: If the wireless router and any terminal are not connected within the third preset time, the wireless router is turned off.

If it is detected that the wireless router is not connected to any of the terminals, it indicates that the current wireless router is in an idle state, thereby turning off the wireless router to reduce power consumption.

Further, after detecting that the wireless router is not connected to any of the terminals, waiting for a period of time (third preset time), if the wireless router does not connect with any terminal during the period, the wireless is turned off. Specifically, when it is detected that the connection between the wireless router and the terminal is completely released (that is, when the wireless router is detected to be disconnected from any terminal), a shutdown timer is started, and if the shutdown timer expires, the wireless The router establishes a connection with any terminal. Then, the timer is turned off, and the process of step 201 is repeated. If the shutdown timer expires, the wireless router is turned off.

In the embodiment of the present invention, the wireless router can detect whether the wireless router is connected to the terminal, and when the wireless router and any terminal are not connected within a preset time, turn off the wireless router; thereby making the wireless router idle. It can be turned off automatically, saving energy and avoiding inefficiencies.
